flux fails to color half of my display which has two displayport connections (displayport 1.4 tiles)

Flux only works on half of my display. The display is a dell 8k display (up3218k) which has two displayport connections (which I believe uses the displayport 1.4 tiled display feature). It appears that flux is only changing the color on one of the tiles. Also I believe dell has put out some 5k monitors that also use this tile feature.

Can this be fixed? or is anyone aware of any workarounds for this kind of issue?

I also tried microsoft's night light and it had the same issue and even the same pattern.

I just tried this on a different computer with an Nivida GTX 1080 card connected to the same two displayport w/ tiling 8k display and it worked fine, coloring the entire screen. Seems like its either an AMD driver issue or a f.lux + AMD driver issue.
